Computernetzwerke ermöglichen die Kommunikation der darin zusammengeschlossenen Systeme untereinander. Das Buch vermittelt grundlegendes Wissen über die Funktionsweise moderner Computernetze und deren verschiedenen Komponenten. Ausgehend von einführenden Kapiteln zur Informationstechnik (IT) und zur Computervernetzung erläutert der Autor zunächst die Grundlagen von Protokollen und deren Einordnung in etablierte Referenzmodelle. In diesem Kapitel wird außerdem der Ablauf der Kommunikation im Computernetzwerk und der Weg beschrieben, den die Nutzdaten durch die einzelnen Protokollschichten nehmen. Den einzelnen Schichten der Netzarchitektur, von der untersten Schicht, der Bitübertragungsschicht, bis zur obersten Schicht, der Anwendungsschicht, sind dann die folgenden fünf Kapitel gewidmet. Zu den behandelten Protokollen gehören Netzwerktechnologien wie Ethernet, WLAN, Bluetooth sowie die jeweiligen Übertragungsmedien. Ein eigenes Kapitel führt in die Netzwerkvirtualisierung mit VPNs und VLAN ein. Am Schluss des Buchs finden Leser eine Übersicht über die wichtigsten Kommandozeilenwerkzeuge, die benötigt werden, um Netzwerke zu konfigurieren und Netzwerkprobleme zu analysieren. Das Buch erscheint in der Reihe „IT kompakt“. Diese Werke zu wichtigen Konzepten und Technologien der IT-Branche zeichnen sich dadurch aus, dass sie die Themen fundiert und zugleich praxisorientierten darstellen. Ziel des Buches ist daher eine an der Realität orientierte Beschreibung von Computernetzwerken, die die wichtigsten Technologien in einem klaren Zusammenhang und anhand von aussagekräftigen Beispielen und vielen Abbildungen behandelt. Die vierte Auflage wurde durchgängig aktualisiert und korrigiert. Neu hinzugekommen sind unter anderem Abschnitte zu den Themen IPv6 und HTTP/2.

Cloud computing is a buzz-word in today’s information technology (IT) that nobody can escape. But what is really behind it? There are many interpretations of this term, but no standardized or even uniform definition. Instead, as a result of the multi-faceted viewpoints and the diverse interests expressed by the various stakeholders, cloud computing is perceived as a rather fuzzy concept. With this book, the authors deliver an overview of cloud computing architecture, services, and applications. Their aim is to bring readers up to date on this technology and thus to provide a common basis for discussion, new research, and novel application scenarios. They first introduce the foundation of cloud computing with its basic technologies, such as virtualization and Web services. After that they discuss the cloud architecture and its service modules. The following chapters then cover selected commercial cloud offerings (including Amazon Web Services and Google App Engine) and management tools, and present current related open-source developments (including Hadoop, Eucalyptus, and Open CirrusTM). Next, economic considerations (cost and business models) are discussed, and an evaluation of the cloud market situation is given. Finally, the appendix contains some practical examples of how to use cloud resources or cloud applications, and a glossary provides concise definitions of key terms. The authors’ presentation does not require in-depth technical knowledge. It is equally intended as an introduction for students in software engineering, web technologies, or business development, for professional software developers or system architects, and for future-oriented decision-makers like top executives and managers.

Xamarin Mobile Application Development is a hands-on Xamarin.Forms primer and a cross-platform reference for building native Android, iOS, and Windows Phone apps using C# and .NET. This book explains how to use Xamarin.Forms, Xamarin.Android, and Xamarin.iOS to build business apps for your customers and consumer apps for Google Play and the iTunes App Store. Learn how to leverage Xamarin.Forms for cross-platform development using the most common UI pages, layouts, views, controls, and design patterns. Combine these with platform-specific UI to craft a visually stunning and highly interactive mobile user experience. Use Xamarin.Forms to data bind your UI to both data models and to view models for a Model-View-ViewModel (MVVM) implementation. Use this book to answer the important question: Is Xamarin.Forms right for my project? Platform-specific UI is a key concept in cross-platform development, and Xamarin.Android and Xamarin.iOS are the foundation of the Xamarin platform. Xamarin Mobile Application Development will cover how to build an Android app using Xamarin.Android and an iOS app using Xamarin.iOS while sharing a core code library. SQLite is the database-of-choice for many Xamarin developers. This book will explain local data access techniques using SQLite.NET and ADO.NET. Build a mobile data access layer (DAL) using SQLite and weigh your options for web services and enterprise cloud data solutions. This book will show how organize your Xamarin code into a professional-grade application architecture. Explore solution-building techniques from starter-to-enterprise to help you decouple your functional layers, manage your platform-specific code, and share your cross-platform classes for code reuse, testability, and maintainability. Also included are 250+ screenshots on iOS, Android, and Windows Phone and 200+ C# code examples with downloadable C# and XAML versions available from Apress.com. This comprehensive recipe and reference book addresses one of the most important and vexing problems in the software industry today: How do we effectively design and develop cross-platform mobile applications?

The management of telecommunications networks and services is one of the most challenging of software endeavors—partly because of the size and the distributed nature of networks; partly because of the convergence of communications techno- gies; but mainly because of sheer complexity and diversity of networks and services. The TM Forum s Solutions Frameworks (NGOSS) help address these challenges by providing a framework for the development of management applications—those software applications that provide the building blocks for management solutions. The members of the TM Forum have elaborated many parts of NGOSS to make it practical—including in the area of information modeling, process analysis, and c- tract de?nition. This book further elaborates NGOSS by examining the challenging area of interface design. One of the costs of deploying a new service is the cost of integrating all the necessary applications into an effective software solution to manage the service. This cost has been dubbed the “integration tax” and can turn out to be ?ve times the capital cost of procuring the management software in the ?rst place. From their long experience of the design and standardization of management applications, the authors have extracted a core set of design patterns for the dev- opment of effective and consistent interfaces to management applications. Adopting these patterns across the industry could reduce the learning curve for software - velopers and allow service providers and systems integrators to rapidly and reliably deploy management solutions and thereby markedly reduce the integration tax.
